MECHANISM FOR MANUFACTURING WASHERS.

SPECIFICATION forming part of Letters Patent No. 270,301, dated January 9, 1883.

Application filed April 20, 1881.

To all whom it may concern:

Be it known that I, TIMOTHY GINGRAS, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful'lmprovements on Mechanism for Mannfacturing Leather Washers; and I do hereby declare that the following description of my said invention, taken in connection with theaccompanying sheet of drawings, forms a full, clear,,and exact specification, which will punch and a part of the carrier; Fig. 3, a de- 'tail plan view of a carrier adapted to rotate,

and Fig. 4 a vertical section through-the lat-. ter form of carrier and the hopper connected therewith.

It has been customary to'interlock the ends of the washer and compress the same by a puucher and die for the purpose of uniting them more firmly; but the banding of the successive washers to these compressing de- I vices is a tedious'and troublesome procedure.

To obviate this inconvenience I employ a carrier for said washers, which may be either a straight plate or board, (3, Figs. 1 and 2, provided with a longitudinal series of openings, D, and adapted to be drawn lengthwise between the die and the punch, or a disk, N, having a circular series of openings, 0, and a central hole, 0, which allows said disk to turn about an axis, this disk-shaped carrier bein shown in Figs. 3 and 4.

'J designates the punch; F, the die; J, a fixed guide stud, which protrudes through each washer as the punch forces said washer down through the carrier and into the central recess of said die; L, a yielding block against which said plunger bears in its descent; j j,

pins which connect said block toa platethat rests on a spring, M, preferably of india-rubber.

The strip or plate 0 is provided on one edge with notches E, arranged at such intervals as to regulate by engagement with a fixed stud,

H, on the die F the presentation of the washers successively to the punch and die.

The openings D are caused to flare upward, and the washers I are nearly equal in diameter to the upper diameter of said openings. Consequently the washers will remain in the latter tilldriven down by the plunger.

guide-stud J, where they remain until plate The elasticity of spring M will then lift them above the face of die F. The movable parts Land j j, before referred to, are suitably guided.

When the disk N is employed its axis must be at such a distance from the punch and die that the openings 0 will be presented successively over said die,vwhen said disk is intermittently rotated about said axis. I employ 'a hopper, P, to supply said openings with washers; but they may be supplied in any other convenient manner.

The carrier 0 or N may be operated by hand or by any mechanism suitable to the intermittent motion required.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In combination with a punch and a yielding die, a carrier having a series of openings for receiving washers and successively presenting them under a punch and over a die, for the purposes set forth.

2. In combination with a punch, die, and fixed stud, H, a carrier, 0, having guidenotches E at regular intervals in one of its edges, said notches being adapted to engage with said stud, for the purpose set forth.

In testimony that I claim the foregoing as 'my invention I have hereto set my hand in the presence of two subscribing witnesses.

TIMOTHY GINGBAS.
